The Greater Mekong Subregion (GMS) comprises Cambodia, the autonomous regions of Guangxi and Yunnan in the People’s Republic of China (PRC), the Lao People’s Democratic Republic, Myanmar, Thailand, and Viet Nam. Economic growth in the GMS countries over the last 2 decades has been remarkable, averaging 7.5 % of gross domestic product (GDP) per capita at purchasing power parity between 1992 and 201 (AD4B 2016). During this period, the GMS nations have achieved dramatic reductions in poverty and admirable increases in food security.
